Hard in the context of the present invention means at least harder than filaments or staple fibers themselves that do not have hard fibers. Preferably, the material used to produce the fibers has a Mohs hardness of at least 2.5, more preferably at least 4, and most preferably at least 6. Examples of suitable hard fibers are glass fibers, mineral fibers or metal fibers.

As an advantage, a fabric including a fiber having a small dpf has improved comfort. Preferably, the fineness is 20 dpf or less, more preferably 10 dpf or less, and most preferably 5 dpf or less. Good results are obtained when the fineness of the first yarn is at least 10 dtex, preferably at least 40 dtex, more preferably at least 70 dtex. The maximum fineness of the first yarn is determined only for practical reasons, and is preferably 7500 dtex or less, more preferably 5000 dtex or less, and most preferably 2500 dtex or less.

For example, a glove comprising a fabric made from the yarn of the present invention having a fineness between 300 dtex and 500 dtex is not only thin and light, but also has good cutting resistance when handling small objects while at the same time being worn by the wearer Allow for more dexterous movement.

本発明の糸はまた、少なくとも１本の弾性フィラメント（すなわち、伸びかつ復元するフィラメント）を含む。弾性フィラメントは、上記弾性フィラメントの周囲のさやを形成する他のタイプのフィラメント及び／またはステープルファイバーで覆うこともできるが、弾性フィラメントを実際に上記さやで完全に覆うことは重要ではない。   The yarns of the present invention also include at least one elastic filament (ie, a filament that stretches and restores). The elastic filament may be covered with other types of filaments and / or staple fibers that form a sheath around the elastic filament, but it is not important that the elastic filament is actually completely covered with the sheath.

本発明の糸の中の弾性フィラメントは、１本または複数本の個別のフィラメントまたは１本または複数本の合体したフィラメント集団の形で存在しうる。しかし、ただ１本の合体したフィラメント集団を用いるのが好ましい。１本または複数本の個別のフィラメントとして存在するにせよ、１本または複数本の合体したフィラメント集団として存在するにせよ、弛緩状態にある弾性フィラメントの総合線密度は、好ましくは、８〜５６０ｄｔｅｘの間であり、好ましい線密度の範囲は１７〜５６０ｄｔｅｘの間、より好ましくは２２〜２２０ｄｔｅｘの間、さらにより好ましくは４０〜２２０ｄｔｅｘの間、さらには４４〜２２０ｄｔｅｘの間、もっとも好ましくは４４〜１５６ｄｔｅｘの間である。本発明の物品がこの好ましい範囲内の繊度を有する弾性フィラメントを含む場合、上記物品の切断抵抗が向上することが見出された。   The elastic filaments in the yarns of the present invention may exist in the form of one or more individual filaments or one or more combined filament populations. However, it is preferred to use only one united filament population. Whether present as one or more individual filaments or as one or more combined filament populations, the total linear density of the elastic filaments in the relaxed state is preferably between 8 and 560 dtex. The preferred linear density range is between 17 and 560 dtex, more preferably between 22 and 220 dtex, even more preferably between 40 and 220 dtex, even between 44 and 220 dtex, most preferably between 44 and 156 dtex.

It may be. Examples of the woven fabric include plain weave, cocoon, matte weave and twill fabric. The knitted fabric can be flat knitted, for example a single jersey or double jersey fabric, or warp knitted. An example of a nonwoven fabric is a felt fabric. Further examples of woven, knitted or non-woven fabrics and methods for their production are described in chapters 4, 5 and 6 of “Handbook of Technical Textiles”, ISBN 978-1-59124-651-0, the disclosure of which Which is incorporated herein by reference. Descriptions and examples of three knitted fabrics are described in Chapter 11 of the same handbook, and more specifically in section 11.4.1, the disclosure of which is incorporated herein by reference.

好ましくは、本発明の布帛は、編物または織物である。丸編物または縦編物（ｗａｒｐ ｋｎｉｔ ｆａｂｒｉｃ）、平編物または平織物の場合に、良好な結果が得られた。そのような布帛は、切断抵抗が向上したまま、柔軟性および軟らかさの度合いが増大することが見出された。平編は、手袋を作るのに用いた場合、特に有利であることが判明した。   Preferably, the fabric of the present invention is a knitted fabric or a woven fabric. Good results have been obtained with circular knitted or warp knitted fabrics, flat knitted fabrics or plain woven fabrics. Such fabrics have been found to increase the degree of flexibility and softness with improved cutting resistance. Flat knitting has been found to be particularly advantageous when used to make gloves.

ゲージが１８以上という大きさの編機を利用して、高分子糸（すなわち、ガラス繊維もスチール繊維も含まず、かつ高度の切断抵抗を有する糸）から布帛を製造することはこれまで不可能であった。そのような高ゲージの機械では、低い繊度、例えば、４００ｄｔｅｘ未満の糸しか使用できない。しかし、低い繊度の糸を使用したのでは、得られた布帛の切断抵抗も減少する。それゆえに、耐切断特性を有する布帛を製造するのに、これまでゲージが１３以下の編機が使用された。   It has never been possible to produce fabrics from polymer yarns (ie yarns that do not contain glass or steel fibers and have a high degree of cutting resistance) using a knitting machine with a gauge of 18 or more. Met. Such high gauge machines can only use yarns with low fineness, for example less than 400 dtex. However, the use of low fineness yarns also reduces the cutting resistance of the resulting fabric. Therefore, knitting machines having a gauge of 13 or less have been used so far to produce fabrics having cut-resistant properties.

It has been found that fabrics can be produced. Fabrics having such high cut resistance can be produced from the yarns of the present invention on commonly used, for example, 15 or 18 gauge knitting machines.
